Title: Servo Booster for Vehicle Braking Systems
IPC: B60T13/57
Filed: 1978-07-08
Abstract: A problem which arises with conventional poppet valve assemblies for servo boosters is that a strong spring for retracting the input rod and locating a bead of the valve member can damage the resilient valve head prior to insertion of the valve assembly into the valve body. The problem is overcome by providing an abutment (14) on the valve body (1) for the spring (13), and by locating the valve member bead (19) by a retaining ring (20) having a snap-engagement with the valve body. The abutment (14) is spaced rearwardly from the retaining ring (20) so that prior to insertion of the valve assembly into the valve body the spring (13) is under a reduced load and exerts a reduced force on the valve head (17) which is less likely to damage it. <IMAGE>
